Velocity Model Layer Cake Two Way Time Depth Converter
Depth from two-way time through a layer-cake velocity model.
Description
Depth from two-way time through a layer-cake velocity model.
Velocity Model Layer Cake Two Way Time Depth Converter is a focused tool for the following task. Depth from two-way time through a layer-cake velocity model. It reports z, TWT from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Velocity Model Layer Cake Two Way Time Depth Converter
Use this seismology calculation to reproduce a stated convention, screen observations, or compare scenarios whose units, coordinate conventions, catalog selection, and model assumptions are known.
- V_i
- Required list. Interval velocities top-down.
- h_i
- Required list. Layer thicknesses.
The cited overview of Seismic tomography supplies background for the terminology and domain context used by this tool.1
How Velocity Model Layer Cake Two Way Time Depth Converter works
Depth from two-way time through a layer-cake velocity model. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- z (m)
- Returned number in m. Total model depth.
- TWT (s)
- Returned number in s. Two-way time to the base.
Limitations and assumptions
- Earth structure, source geometry, path effects, site response, instrument response, catalog completeness, uncertainty, and the fitted range can dominate the accuracy of simplified seismic calculations.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
For analysis or hazard decisions, retain uncertainty and provenance and compare the result with waveform processing, calibrated regional models, and guidance from qualified seismologists or the responsible agency.
